Many of us like to look through the news feed before going to bed or watch funny videos on our smartphone. After that, the phone is often placed on the charge and placed nearby, or completely sticks under the pillow, where he will have to charge until the morning. However, not everyone knows that such a mode of charging the phone is harmful for both the person and the device itself, and in this article we will discuss why it is impossible to sleep with the phone being charged under the pillow.
Why not put the phone while charging under the pillow?
A lot of research around the world confirms that the constant presence of a smartphone in the field of radiation is dangerous to human health. Despite this, most people continue to keep their gadgets in their immediate vicinity day and night, not a distance from them for a meter. However, sleeping with a phone that is being charged under a pillow is not only harmful for this reason.
Studies have confirmed that the negative radiation of modern mobile technology:
- Has a detrimental effect on user sleep
- Increases user anxiety
- May contribute to jet lag.
- May increase the likelihood of developing cancers
Reference! To limit the effects of radiation, it is recommended to remove a cell phone from yourself at least one meter before bedtime.
If we talk about the harm that brings the "night" method of charging the smartphone itself, then there are many nuances. Many, probably, noticed that at long charging the back part of the device heats up noticeably. It comes from the intensive work of the battery. It should be immediately noted that such overheating in itself negatively affects the operation of the device, causing “glitches” and braking of the operating system, as well as significantly reducing the operating time of the main parts of the smartphone.
If the phone is under the cushion, in an airless static environment, the battery does not actually cool down, which leads to even more overheating.
Reference! "Heating" the device when charging up to 60 degrees Celsius in just three months of operation can "kill" up to 40% of the total battery capacity.
Summarizing all the above, we can say that the smartphone, which is constantly on charge throughout the night, does not receive sufficient cooling of the battery is actually doomed to an early failure. Of course, constantly connected charging does not mean that the phone heats up continuously and recharges. Controllers that are responsible for a sufficient level of charge in modern smartphones most often work properly, but even they do not solve the problem completely, because even when the screen is locked, the device’s energy is still spent on maintaining the search for a communication signal, data transmission sensors, Wi-Fi and others.
Fire from a smartphone? Surprisingly, such instances of history are known. They do not happen so often, but sometimes after determining the cause of the fire, experts conclude that it could be an overheated smartphone battery. In addition, there are cases of detonation of smartphones of one well-known manufacturer, but this is already a topic for a separate material.
Where is it safe to put the phone at night?
There is a fairly simple answer to this question: the further, the better. The distance of less than one meter between the user and the telephone leads to the fact that the negative radiation of the device continues to affect the body of its owner, which then affects the form of not too serious, but still unpleasant health problems.
If we talk about fire safety, then you should not put the device on soft surfaces, cover it on top with any materials. It would also be good to remove the cover from the phone before charging. To bring the phone to full discharge today is no longer relevant: a full discharge cycle does not affect the operation of modern batteries.
